Detailed Description

IDataSaver implementation that streams CSV packets over UART.

Note

When to use: log data to an external serial data logger when file systems (SD/SPI flash) are unavailable or you need live passthrough.

Definition at line 16 of file DataSaverSDSerial.h.

Constructor & Destructor Documentation

DataSaverSDSerial()

DataSaverSDSerial::DataSaverSDSerial

(

HardwareSerial &

SD_serial

)

Create a saver that streams CSV over UART to an external data logger.

Parameters

SD_serial

Hardware serial interface connected to the logger.

Note

When to use: quick logging to a serial-equipped recorder when file systems are unavailable.

Definition at line 28 of file DataSaverSDSerial.cpp.

Member Function Documentation

saveDataPoint() [1/2]

int DataSaverSDSerial::saveDataPoint ( const DataPoint & dataPoint, uint8_t name )

overridevirtual

Write a timestamped value to the serial logger.

Parameters

dataPoint	Data point to transmit.
name	8-bit channel identifier transmitted alongside data.

Note

When to use: continuous logging after the external logger is ready.

Implements IDataSaver.

Definition at line 32 of file DataSaverSDSerial.cpp.

saveDataPoint() [2/2]

virtual int IDataSaver::saveDataPoint ( float data, uint32_t timestamp_ms, uint8_t name )

inlinefinalvirtual

Convenience overload to construct and save a data point.

Parameters

data	Measurement value.
timestamp_ms	Timestamp of the measurement in milliseconds.
name	8-bit source identifier.

Note

When to use: callers that have raw values but not a DataPoint object.

Reimplemented from IDataSaver.
